“…Using a sample of 136 male Iberian ibexes (Capra pyrenaica) from the Sierra Nevada Natural Space (southern Spain), we assessed whether mange affects body weight, which shows markedly seasonal variations, but also examined the effects of mange on hematologic and serum chemistry values of affected animals. Because ibexes in the Sierra Nevada experience strong seasonal changes in body reserves (Serrano et al 2011) and such body stores are correlated to some hematologic parameters (Serrano et al 2008), we expected that mange may drive the seasonal hematologic profile of this mountain ungulate.…”

“…Both KM and KF are positively correlated to nutritional status in Iberian wild goats (Serrano et al 2008b) and to body condition in a great range of mammals of different body sizes (from roe deer to moose, Serrano et al 2008a). As predicted, heavier goats (skeletally bigger and fatter) had more KM (R 2 =0.73, F 1,461 =1,281; p<0.01, linear relationship between body weight and KM) and KF (R 2 = 0.26, F 1,461 = 159.5; p < 0.01 following the same procedure) than lighter ones.…”

“…In addition, the kidney mass of this Caprinae species is directly related with Period contrasted periods of fat storage, from November to April (when goats depleted their fat stores) and from May to October (when goats recovered their fat stores). In bold, the selected model the serum total proteins (Serrano et al 2008b), suggesting that the increased availability of food in the warm season (the main plant growth period) will stimulate the rapid recovery of the kidneys and their anabolic and filter activities and hence protein stores in this wild goat species. According to our second prediction, sexual differences were observed in the amount of KFs and Ks and in the period in which body stores change from negative to positive values.…”

We studied the factors that determined kidney fat stores (KFs) and kidney stores (Ks)-defined as the residuals from the linear regression of kidney mass and kidney fat, respectively, on body weight-in 463 Iberian wild goats (Capra pyrenaica) from the Sierra Nevada (southern Spain). Despite the fact that body stores in both sexes were highest during the warmest months of the year and lowest during the coldest months when food resources are limited, the observed pattern was sex-and agedependent. The KFs of male goats fell more than those of females in winter, and the yearlings of both sexes needed one season more than young or adults to restore their KFs.Goats of all age classes showed the same seasonal patterns in their Ks, although Ks were lower in females than in males throughout the yearly cycle. In addition, we found strong delayed effects of both snowfalls and population density on body stores, and in years with a lot of snow, goats' KFs reached their lowest levels in the current winterspring, but the highest in the following summers and autumns. This pattern was less noticeable in the Ks. Population density negatively affected the body stores of wild goats, especially in winter, and the amount of snow fallen in the year of birth (cohort effect) did not seem to influence the body stores in our data set. In addition, we Communicated by H. KierdorfElectronic supplementary material The online version of this article (assessed the accuracy of the residuals from the regression between body size and body mass for monitoring body condition of live wild goats and concluded that, although it poorly indicates fat stores, it could be used as a general proxy of body condition. Finally, we discuss the expected effects of climate warming on body stores in this Mediterranean Caprinae species.

“…Kidney fat reserves were assessed following Serrano et al [ 10 ] recommendations. Both fat-free kidney mass (KM) and associated peripheral fat (KF) are positively correlated to nutritional status and body condition of a wide range of mammals including Iberian ibex [ 23 ]. Therefore, we used the residuals from the linear regression between KM and KF as a proxy of body condition.…”

BackgroundBoth parasitic load and resource availability can impact individual fitness, yet little is known about the interplay between these parameters in shaping body condition, a key determinant of fitness in wild mammals inhabiting seasonal environments.MethodsUsing partial least square regressions (PLSR), we explored how temporal variation in climatic conditions, vegetation dynamics and sarcoptic mange (Sarcoptes scabiei) severity impacted body condition of 473 Iberian ibexes (Capra pyrenaica) harvested between 1995 and 2008 in the highly seasonal Alpine ecosystem of Sierra Nevada Natural Space (SNNS), southern Spain.ResultsBottom-up regulation was found to only occur in healthy ibexes; the condition of infected ibexes was independent of primary productivity and snow cover. No link between ibex abundance and ibex body condition could be established when only considering infected individuals.ConclusionsThe pernicious effects of mange on Iberian ibexes overcome the benefits of favorable environmental conditions. Even though the increase in primary production exerts a positive effect on the body condition of healthy ibexes, the scabietic individuals do not derive any advantage from increased resource availability. Further applied research coupled with continuous sanitary surveillance are needed to address remaining knowledge gaps associated with the transmission dynamics and management of sarcoptic mange in free-living populations.
